PECTIN METHYLESTERASE FROM CARROT

The structure was published by Johansson, K., El-Ahmad, M., Friemann, R., Jornvall, H., Markovic, O., and Eklund, H., in 2002 in a paper entitled "Crystal Structure of Plant Pectin Methylesterase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.75 Å and deposited in 2001.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of PECTINESTERASE. This molecule has the UniProt identifier P83218 (PME_DAUCA)search. The sample contained 319 residues which is 100% of the natural sequence. Out of 319 residues 319 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule is most likely monomeric.
